Tony Stewart struck and killed fellow racer Kevin Ward during a Sprint Car race at Canandaigua Speedway in New York. Ward was out of his car and walking toward Stewart under caution.

Tragic news this morning from Canandaigua Speedway in New York, where NASCAR star Tony Stewart was involved in a on-track incident that resulted in the death of 20-year-old Kevin Ward. Ward had climbed out of his car and walked into traffic after a tussle with Stewart sent him into the wall.

Rather than try to dive into analysis, we'll aim you toward a piece by Road & Track contributor Steven Cole Smith at Motorsport.com, which has the most thoughtful reporting we've seen on the accident this morning.

The AP is reporting that Stewart was questioned by local authorities and that no criminal charges are imminent. Stewart was expected to race Sunday in the NASCAR series event at Watkins Glen, but he withdrew and Nationwide Series driver Regan Smith drove in his place.
